STEREOTYPE-CHAS E.

SPECIFICATION forming part of Letters Patent No. 668,374, dated February 19, 1901.

Application filed $eptemhcr 5, 1900; Serial No. 29,073- (No model.)

To all whom it may concern. A

Be it known that I, WILLIAM G. HER'Z, a citizen of the United States,residing atlluntsville, in the county of Madison and State of Alabama, have invented a new and useful Stereotype-Chase, of which the following is a specification.

This invention relates to chases in general, and more particularly to that class used in connection with stereotype-form s,although it will be understood from the following descrip tion that the principles of the invention may be applied to chases for other specific pur poses.

One object of the invention is to provide a construction wherein the quoins at both sides of the chase may be simultaneously operated by means of a single key to grip or release the form, further objects and advantages of the invention being evident from the following description. 7

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a plan view showing the complete chase, a portion of one of the members of the quoins being shownin section to illustrate the man her of holding it in place. Fig. 2 is a section on line 2 2 of Fig.1. Fig. 3 is an enlarged plan view of a corner of the frame of the chase, one of the gear-holding plates being removed to show thegearin end elevation and to illustrate the recess in which the plate is normally seated. Fig. 1 is a side elevation showing the key employed foropcrating the quoins.

Referring now to the drawings, the chase comprises a rectangular metal frame 5, which is cast integral and is adapted to receive the form, which latter is clamped tightly against displacement by means of quoins disposed against two mutually adjacent sides of the frame and comprising members 6 and 7 and members 8 and 9, respectively. The members of each of the quoins have their adjacent faces provided with cams 10, which are oppositely disposed, as shown, so that as one member is slid longitudinally over the opposing member these cams will ride one on another and the outer faces of the members will be separated to broaden the quoin. When the members are moved in the opposite directions,

the cams of one member will take into the interspaces between the cams of the opposing member, and the width of the quoin is thus diminished.

The members 6 and 8 in the present instance are disposed with their outer faces against the inner faces of the mutually adjacent sides 11 and 12 of the frame 5, against which they are held slidably by means of pins 13, which are engaged with the inner faces of the sides 14 and 15 of the frame and lie parallel with the inner faces of the sides 11 and. 12. The pins 13 engage recesses 16 in the. ends of the members 6 and 8 and while holding them against lateral movement permit longitudinal movement thereof.

Against the outer or exposed face of the quoin member 7 is disposed a metallicblock 20, which is adapted to rest against the bottom of the form and which has a number of serrations 21 therein to receive the ends of the column rules of the form. The opposite end of the form rests against the side 15 of the frame, one side of the form resting against the side 14 of the frame and the other side of the form resting against the quoin member 9. Thus if the members 7 and 9 be moved longitudinally in the proper direction their cams will engage with the cams of members 6 and 8 and the members 7 and 9 will move against the block 20 and the side of the form to clamp the form firmly in position. To thus reciprocate the quoin members 6 and 8, the member 8 has a rack-bar 22, engaged with its rear face, said rack-bar lying with its teeth proj ecting inwardly of the frame, while its opposite side is in slidable contact with the inner face of the side 12 of the frame 5, and engaged with this rack is a pinion 24. The pinion 24 has trunnions which are engaged with bearings in plates 25 and 26, which latter are secured in recesses in the opposite faces of the frame 5 and at one corner thereof, said plates lying flush with the outer surfaces of the frame and having their ends projecting inwardly and diagonally of the frame. It is these inwardly-projecting ends of the plates that have the bearings formed therein, and the rack-bar 22 lies with its toothed portion between the pinion and the side 12 of the frame. The quojn member 6 is also provided with a rack-bar 27 which is spaced from the hold the members 6 and 8 against accidental displacement.

The pinion 24 is hollow, as shown, the bore thereof being cross-sectionally angular to receive akey, (shown in Fig. 4,) which key forms a means for rotating the pinion. As the pinion is oscillated the i-ack-bars are reciprocated and the quoin members 6 and 8 are correspondingly moved.

It will be noted that with the present construction the outer faces of the chase-frame 5 are unbroken, so that the strength thereof is preserved, while a singleikey acts to operate both quoins in such manner as to secure the most efficient results.

It will be understood that in practice various modifications of the specific construction shown may be made and that any suitable materials and proportions may be used for the various-parts without departing from the spirit of the invention.

In Fig. 4 of the drawings is shown the key employed in operating the quoins, which consists of a stem 30, which is cross-sectionally angular and has an operating-handle 31.

What is claimed is 1. A chase comprising a frame, quoins disposed against mutually adjacent sides of the frame and each comprising a fixed member and a movable member, a rack-bar carried by the movable member of each quoin and disea e;

posed one across the other, and a single pinion engaged with both rack-bars and adapted for oscillation to operate both movable members.

2. A chase comprising a frame, qu'oins disposed against mutually adjacent sides of the frame and each including a fixed member and a slidable member, a rack-bar carried by the movable member of each quoin, and a single pinion journaled in the corner of said mutually adjacent'sides and engaged with the rack-bars of both movable quoin members, said pinion being adapted for oscillation to reciprocate both movable quoin members simult-aneously.

'3. A chase comprisinga frame, quoins disposed against mutually adjacent sides of the frame and each comprising a member in slidable contact with the frame, said slidable members having each a recess in one end, a

pin carried by the frame and engaged with the recess of each member, rack-bars carried by the slidable members and disposed to cross, plates secured to the frame at the corner of the sides against which the quoins are disposed and projectinginwardly of the frames, and a pinion journaled in said plates and engaged with the rack-bars, said pinion having means for engagement by a key to oscillate the pinion and reciprocate the rack-bars and therewith the slidable quoin members.

In testimony that I claim the foregoing as my own- I have hereto affixed my signature in the presence of two witnesses.

WILLIAM G. HERZ.
